Looking for oil change recommendations for your 1986 GMC C3500? Turn to Firestone Complete Auto Care! We are experts in car care — not just tires. We know the ins and outs of motor oil, too. After all, "Oil is the blood of the engine. It's the #1 thing you can do for your car," says our maintenance technician, Brianna.
Your 1986 C3500’s oil should be changed according to GMC’s recommended oil change intervals. See mileage and month specifics in the above table. Your C3500 may need an oil change right away if your check engine/oil change light is on, you hear engine knocking, smell oil inside the car, or notice excess vehicle exhaust. You may also need an oil change more frequently than GMC recommends if you haul heavy loads, frequent dusty roads, go off-roading a lot, or go at low speeds on long distance trips. In general, being extra-diligent about oil changes won’t damage your GMC C3500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your GMC C3500. GMC has recommendations as to whether conventional or synthetic oil is the best motor oil for your 1986 C3500. Motor oil reduces friction between engine components, maintain proper engine temperature, and keep harmful substances from building up inside the engine. In an oil change service, an auto technician will change your C3500’s oil, replace and recycle your used oil and filter, inspect all of your other filters, top-off important fluids, and visually inspect the rest of the vehicle. You can drive with confidence knowing that we look out for you and your C3500 by taking into account your driving habits, weather and road conditions,
